And the earth and the mountains shall be removed from their places, and crushed with a single crushing. Then on that Day shall the (Great) Event befall. (69:14-15)

And;

﴿إِذَا رُجَّتِ الاٌّرْضُ رَجّاً – وَبُسَّتِ الْجِبَالُ بَسّاً ﴾

When the earth will be shaken with a terrible shake. And the mountains will be powdered to dust. (56:4-5)

It was said that this earthquake will come at the end of the life span of this world, at the outset of the Hour. Ibn Jarir recorded that `Alqamah commented on Allah’s saying,

﴿إِنَّ زَلْزَلَةَ السَّاعَةِ شَىْءٌ عَظِيمٌ﴾

Verily, the earthquake of the Hour (of Judgement) is a terrible thing.

“Before the Hour.” Others said that this refers to the terror, fear, earthquakes and chaos that will happen on the Day of Resurrection, in the arena (of Judgement), after the resurrection from the graves. This was the view favored by Ibn Jarir.
